Davis, B W

This patent describes a method for recovering oil from an underground oil-bearing earth formation penetrated by an injection well and a producing well, in which method carbon dioxide is injected into the formation to displace oil towards the producing well from which the oil is produced to the surface. This patent describes improvement in injecting into the formation carbon dioxide, the viscosity of which is increased by the presence of a sufficient amount of a polysilylenesiloxane polymer to increase the viscosity at least three-fold.
